rMBP (13-inch 2014) slower than MBA (13-inch 2012)

I bought a new MacBook Pro Retina (13-inch) last month with a 256GB SSD. It came with Mavericks out of the box and on my first boot up, I upgraded it to Yosemite.

Now for some reason, it doesn't feel like a 'Pro' -- as in it feels sluggish, has jittery transitions/animations and everything feels slow. I wouldn't have noticed much, but coming from a MacBook Air (2012) with 4GB of RAM and using it for 2 years, this feels really slow.

My MBA still runs much faster and feels great overall with Yosemite, not the same with rMBP though. Both have OS X 10.10.1 with MBA having more apps installed and rMBP is still kinda new.

Do a clean install of Yosemite...problem solved...issue has been discussed in many threads. I'm assuming you did an app store upgrade of Yosemite. If you've already done a 'clean' install then I'm not sure why you're having issues but this is a very common issue for people that upgraded through the app store.

I did a clean instal when switching from Mavericks to Yosemite and, as I mentioned earlier, I saw the same jitteriness on the 5k imac!

Definitely not seeing anything noticeable on mine...seems to affect some systems while others go untouched...I'm very picky about these sorts of things if it was there I would have noticed it by now. (rmbP late 2013 15" w/ 750m)

I would like to add my comments to differences between my 15" late 2013 MBP and my early 2014 11" MBA.

I believe that Yosemite runs much better on the 11" MBA than on 2013 rMBP for the following reasons:

- No WiFi Disconnects on Air. Still see them on the rMBP
- New MS Outlook always maintains connections with servers on MBA. Not so with on the rMBP. I am always having to enter passwords.
- Issues with ejecting a mounted drive on the rMBP. Never on the Air.
- Issues with screen coming back after short sleep on the rMBP (also was present on Mavericks). Never have had this issue on the Air.

I would say that for less than half the price of the rMBP, the MBA is better and less buggy computer.

Someone else is going through the same. I just hope Apple gets out a fix soon for this!

This isn't a problem with computational performance per se. Yosemite has purposefully slowed down animations for some UI transitions; this is a design choice just like how there are slower home screen animations in iOS7 & 8. The slower animation in the "About My Mac" window is evident on my machine as well (rMBP late-2013).

If I were you I would just try to get used to it. I honestly don't think you'll spend too many hours of your time transitioning between tabs on "About My Mac." The machine is blazing fast for everything else just like how Queen 6 noted.

EDIT: I do think it's true that retina scaling affects the smoothness of other UI animations, especially the expose/mission control animation. The expose animation is visibly choppy on the retina screen, but when I close the laptop and use only my connected Thunderbolt Display which does not need scaling, the animation is buttery smooth. This has been an issue ever since the first retina machines came out IMO. I used to own a MacBook Air, and the Airs had no such framerate stuttering even with the inferior HD 5000. This issue is still not something that would make me choose a MacBook Air over a MacBook Pro.

Any suggestions on how to fix this MacBook Pro?

Sorry to hear you're having performance issues. I'm running a 2014 13" MacBook Pro 128GB HD and 8GB of Ram. No lag issues here, no issues with transitions or anything of the such.

One point I do want to make is I'm having some sporadic issues with Wifi. It'll either connect and boot me off, or connect and run extremely slow. Other than that I'm loving this laptop. If you're having issues, contact an Apple store or return it and purchase a replacement. Apple probably won't fight you on doing that.
